Newton is proud to contribute to the transformation of the unique, Grade I listed Cambridge House in Piccadilly as it undergoes conversion into one of London’s grandest hotels. The 18,000m2 scheme includes six adjacent Grade II listed residences. A four-level basement will accommodate a spa, it will also house the back-of-house and servicing areas.

The Project

In order to deliver a reliable, watertight solution for this project, Newton worked closely with architects PDP London and leading enabling works contractor Deconstruct UK throughout the design and installation.

There are three main buildings where extensive excavations are taking place. They required different waterproofing solutions for new basements and existing structures, all up to four storeys below ground.

The Solution

Buildings 1 and 3 are both benefiting from full Newton CDM System cavity drain membrane waterproofing. This will capture, depressurise and remove any ingressing groundwater via a series of Trojan-Pro pump chambers.

Building 2 utilises numerous products across new/existing structures, including 403 HydroBond, installed by NSBC Maclennan Waterproofing, and 315 Polymer-Waterbar to the new concrete attenuation tank. This will also be coated internally with the 103-S liquid membrane.

The team also used the same two products alongside the flexible 107F liquid membrane and 106 FlexProof to waterproof construction joints where the existing brick structure meets the new concrete slab.

The Result

As of June 2021, the waterproofing installation is underway and on track on all three buildings. Newton’s site services team delivers exceptional quality assurance on the installation of our products. They also provide comprehensive training for the installation process.

Testimonial

“Newton Waterproofing have been working with Deconstruct to provide waterproofing design and solutions at Cambridge House. The project encompassed forming new deep Basement excavations, Grade 1 and Grade 2 listed structures requiring significant interventions and all requiring a Grade 3 level of waterproof protection. Newton have been involved from the outset and have provided a first class service to ensure we provide a robust solution to this prestigious project.” Mark Makinson, Project Director – Deconstruct UK Ltd
